drm/ttm: remove ttm_tt_destroy_common v2
Move the functionality into ttm_tt_fini and ttm_bo_tt_destroy instead.
We don't need this any more since we removed the unbind from the destroy
code paths in the drivers.
Also add a warning to ttm_tt_fini() if we try to fini a still populated TT
object.
v2: instead of reverting the patch move the functionality to different
places.
